'EYELETING MACHINE.

Application filed February 19, 1914, Serial No. 819,885. Renewed April 1'7, 1925.

To all whom it may concern:

Be it known that I, EDWARD E. Corn, a

citizen of the United States, residing.at Holland, in the county of Ottawa and State 6 of Michigan, have invented certain Improvements in Eyeleting Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the draw- 10 ings' indicating like parts in the several figures. 4

This invention relates to machines for insorting fasteners such as eyelets in a plurality of layers ,of material and clenching 5 the endsof their barrels between adjacent layers of the material.

Eyelets inserted in this fashion in shoe uppers are known as blind.or invisible eyelets. Blind eyelets are inserted through the outer layer, that is, the upper leather, so

set in shoe uppers after the layers .of the uppers'have been stitched together, the setting being performed by means of a setting tool of such a character that it may be introduced from one side of the shoe upper through a lacing hole unched in the upper.

40 tool is positioned between adjacent layers of the upper where it meets the entering end of the eyelet barrel and clenches the eyelet barrel between the layers; When so inserting blind or invisible eyelets considerable difliculty has been experienced in properly locating the clenching shoulder of the tool relatively to the layers of the shoe upper so as to produce satisfactory clenching of the eyelets. For example, it has sometimes happened that the upper. leather would pass too far beyond the clenching shoulder of the tool with the result that the eyelet would be clenched beneath the reinforcing stay, or partly beneath and partly above the stay,

so that the holding power of the eyelet was much reduced.

It is accordingly an object of the present invention to provide a fastener inserting machine organized for setting blind or invisible eyelets and having a setting device of a character which will ensure the proper relative position of the work and the clenching shoulder of a fastener inserting tool so that the fasteners will be uniformly clenched between the desired layers of material. With this object in view a feature of the invention comprises a fastener setting tool having a rigid flange or abutment arran ed positively to limit relative movement of t e outer layer. of the work and the setting tool prior to and during the insertion of the fastener. This abutment should be spaced from the clenching shoulder of the tool a distance substantially equal to the thickness ofthat layer or of those la ers of the work beneath which the fastener 15 to be clenched. In the illustrated device this rigid abutment is integral with the remain- ,der of the setting tool but it should be understood that it is not necessarily so constructed. Moreover, while the invention is disclosed as embodied in a machine having a separate punch and set, it should be understood that the "invention is not limited to a machine so organized.

The above and other features of the invention will be best understood and appreciated from the following description of a preferred embodiment thereof selected for purposes of illustration and shown in the accompanying drawings, in which By relative moveme of the tool and the shoe upper the clenching shoulder "of the Fig. 1 is a view in perspective of the operative parts of a power eyeleting machme having the present invention embodied therein,

Fig. 2 is a view partially in section on an enlarged scale showing the setting tools in operative relation to the work,

Fig. 3 is a view in perspective setting tool, and

Fig. 4 is a fragmentary-view showing portions of a shoe in which invisible eyelets are set. 3

In the accompanying drawings the invention is illustrated as embodied in the well known Universal eyeleting machine shown,

of my novel for example, in Letters Patent of the United tion of Seymour Field. The machine frame 2 is provided with vertical ways for a reciprocatory plunger 4 which carries the lower set 16 having a center spindle 18. A pair of oscillating levers carry respectively the upper setting tool and a punch 20. The lever 8 which carries the punch 20 is arranged to swing vertically to perforate the work in co-operation with a punching die 22. After the punching operation the punch lever 8 and the punching die 22 are moved to an inoperative position and the lever 6 which carries the upper setting tool is moved laterally over the punched hole, then downwardly to engage the work, and then laterally to feed the punched work into alinement with the lower set 16. Finally the lower set 16 is moved upwardly to eflect the setting operation. a a

The machine is provided with a work table 19 which is secured to the frame 2 and perforated to permit the passage of the operating tools. A presser foot 26 cooperates with the work table for hold ng the work stationary between the successive feeding movements of the setting tool. A raceway 24 is arranged to supply eyelets to the spindle 18 of the lower set 16 during the initial upward movement of this member and then. is moved rearwardly to an inoperative position. Operating mechanism for the parts just described may be provided as disclosed in said Letters Patent No. 603,023.

The illustrated machine, which is organized in accordance with the present invention and is shown as setting invisible eyelets, has its lower set 16 shaped at its upper end to fit and support the flange of the particular eyelet it is desired to insert. The upper setting tool of the illustrated machine is formed with a heavy flange 10 constituting a rigid shoulder or abutment from the can ter of which projects a cylindrical member 12 shaped to form a clenching shoulder, which constitutes the actual clenching surface, and having an extension or leader 14 of reduced diameter extending from the clenching surface and serving as a pilot. The portion 12 is made of a len h substantially equal to the thickness 0 the upper leather of the shoe and of substantially the same diameter as, or slightly greater than, the diameter of the lacing hole. The lower end of the cylindrical portion 12, where it merges into the pilot portion 14, is curved, as shown in cross-section in Fig. 2, and forms the clenching shoulder. In the eyelet inserting operation the upsetting or clenching portion 12 is forced, by relative movement of the work and the tool, into the previously punched hole, the work stretching slightly, if necessary, and the hole is completely filled. Thus the clenching shoulder of the tool is positioned in substantially the plane of the inner surface of the upper leather 30, the flange or abutment 1O positively limiting the movement of the work relatively to the clenching shoulder, so that the eyelet is properly clenched between the layers. In the machine disclosed these sets constitute a part of the organization of a machine equipped with punching means so that the complete operation of punching, feeding and inserting is carried out in the same machine. As herein shown the punch 20 is made of substantially the same diameter as the portion 12 of the upper set or slightly smaller so that the hole produced in the outer part 30 of the quarter will have to be slightly stretched as the upper layer of the work passes over the clenching shoulder while the hole punched in the lining 32 will closely approximate the outer diameter of the eyelet barrel.

In operating the machine herein disclosed in inserting invisible eyelets the lined and stitched quarter of a shoe is presented to the machine with the point where an eyelet is first to be set in alinement with the punch 20. The machine is thereupon started and a hole punched through both parts of the quarter as shown in Fig. 2. The upper set is then introduced into the punched hole and the work is then advanced to setting position by the transverse movement of the upper set. Meanwhile an eyelet has been taken from the raceway by the lower set 16. The lower set is then elevated to meet the upper set, the position of these parts at the conclusion of the setting operation being shown in Fig. 2. In this operation the eyelet barrel is centered by the leader or pilot 14 which forces the spindle 18 into the lower set. In the further relative move ment of the setting tools the eyelet barrel is forced against the transverse clenching surface or shoulder of the upper set, which at this time is located between the layers of material where the eyelet is to be clenched, and the end of the barrel is turned outwardly and clenched upon the covered surface of the lining 32, the flange or abutment 10 limiting the movement of the work past the clenching shoulder of the tool. In this operation the lining material about the margin of the hole may be somewhat compressed between the lower set 16. and the flange 10 of the upper set or, more strictly, the portion of the leather'30 which is supported by the flange or abutment 10. This causes the diameter of the hole in the Km ing to be somewhat reduced so that there will be no looseness of the eyelet in the hole. The remaining eyelets are set by repetitions of the operations above explained and when the last eyelet has been set the upper is removed from the machine in a finished condition and requires no further stitching.

No claim is made in this application to the novel method disclosed, since that method is claimed in my co nding appli cation Serial No. 846,111, file June 19, 1914. Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:
